ROC curves. ROC curve for preoperative PTA (optimal cutoff value 32.0°, AUC 0.81), preoperative P3TA (optimal cutoff value 29.9°, AUC 0.92), and preoperative P3TA and basal aneurysm/dyskinesis (AUC 0.94) as predictors of IMR recurrence after undersized mitral ring annuloplasty. The incremental value of preoperative 3DE over 2DE (orange area) in predicting IMR recurrence after mitral annuloplasty becomes apparent immediately. 3D, 3-Dimensional; P3TA, P3 tethering angle; BA/D, basal aneurysm/dyskinesis; AUC, area under the curve; 2D, 2-dimensional; 2CH, 2-chamber; PTA, posterior tethering angle; ROC, receiver operating characteristic; IMR, ischemic mitral regurgitation.
